Abstract Within- and across-country genetic parameters need to be estimated prior to an international genetic evaluation of dairy bulls. A procedure based on the Expectation Maximization algorithm to produce restricted maximum likelihood estimates of such parameters, using national evaluation...
Abstract The present paper describes the effect of heterosis found in a full diallel design 4×4 pure strains of laying hens. There were 36 individually measured hens per combination. In economic terms and with regard to a low food conversion ratio (FCR), positive heterosis was found for egg...
Abstract During three years (experiments 1-3) short-term grazing experiments were performed to study late season herbage intake by dairy cows. Change-over designs were used during experiments 1 and 2 while a continuous design with a covariate period was used in experiment 3. The effect of...
Abstract The basis for using determined values of endogenous ileal protein and amino acid losses in the protein evaluation of pig feeds is reviewed. The amounts of endogenous protein and amino acids in ileal digesta may be determined by numerous methods. These include N-free diets, regression...
Abstract There is a distinction between the terms apparent, true, real, and “net” ileal protein and amino acid digestibility. For low-protein feedstuff's, “apparent” values relate directly to the feedstuff and are accurate estimates of net digestibility. For diluted protein-rich feedstuffs,...
Abstract A total of 2152 hens were fed one of two diets, with 25.0% wheat and 38.7% barley or 50.0% wheat and 13.7% barley. The hens were housed in battery cages with three hens per cage and in two aviary systems with tiered wire floors and litter-Lövsta with two tiers and Marielund with three...
Abstract A study was performed to investigate the effect of environmental temperature (18°C or 28°C) and increasing levels of pea fibre in the diet on digestive tract, visceral organ size, digestibility and energy metabolism in rats. Thirty-six male Wistar rats, initial liveweight (LW) 77-79 g,...
